# unchanged CHANGELOG Yes, the irony is not lost on me. :) ## 2.2.0 - Fix issue where `getOwnPropertySymbols` was expected to always be supported when `Object.assign` was natively supported - Greatly improve typings of handlers ## 2.1.0 - Add [not](README.md#not) and [notWith](README.md#notwith) methods - Ensure that objects with custom prototypes always use the same creator ## 2.0.1 - Fix [#33](https://github.com/planttheidea/unchanged/issues/33) - ensure objects created with `Object.create(null)` do not error - Switch from `babel-minify` to `terser` for minified build ## 2.0.0 Rewrite in TypeScript! **BREAKING CHANGES** - `transform` has changed to be `setWith`, and the signature has changed as well (see [the documentation](README.md#setWith) for details) **NEW FEATURES** - Added [`is`](README.md#is) method for assertion - Added function-first `*With` methods corresponding to each existing method (see [the documentation](README.md#transform-methods) for details) - TypeScript typings **ADDITIONAL CHANGES** - Faster `get`s, `set`s, `merge`s, and `remove`s - Distinct `main`, `module`, and `browser` builds for better universality of consumption ## 1.5.2 - Fix `rollup` build setup with latest `curriable` and `pathington` setups ## 1.5.1 - Return support for `Symbol` keys when using `assign`, `merge`, `remove`, and `set` - Add documentation for `has` method - Improve speed of `add` by eliminating unneeded call to curried wrapper - Improve speed of `merge` by eliminating unneeded extra cloning - Improve speed of `remove` by eliminating unneeded iterations - Allow cloning to work consistently even with data from across realms ## 1.5.0 - Add [`assign](README.md#assign) method ## 1.4.2 - Add `"sideEffects": false` for better tree-shaking in webpack ## 1.4.1 - Update to use `babel@7` (smaller build, slightly better performance) ## 1.4.0 - Add [`transform`](README.md#transform) function - Remove use of native `Object.assign` in favor of local code (faster) ## 1.3.3 - Provide `Object.assign` fallback for IE support without polyfill - Use internal `reduce` method for performance on non-standard objects ## 1.3.2 - Use direct assignment instead of `.push()` when cloning arrays, to prevent breakage when the array has a custom `push` method ## 1.3.1 - Remove benchmark files from published package ## 1.3.0 - Add [`call`](README.md#call) function ## 1.2.1 - Simplify code for `has` ## 1.2.0 - Add [`getOr`](README.md#getor) function ## 1.1.0 - Add `rollup` for building `dist` files - Replace homegrown curry with `curriable` ## 1.0.7 - Improve speed of curried methods by removing unneeded `slice` calls and calling with initial `0` index ## 1.0.6 - Replace `map` with `slice` when shallow-cloning arrays (performance and footprint) ## 1.0.5 - Fix issue with using array keys when using `add` with nested arrays ## 1.0.4 - Ensure that the original object's prototype is retained on `merge` when it is not a standard object ## 1.0.3 - Use custom `splice` for `remove` instead of native (in case item is an extension of an `Array` and has messed with `splice`) ## 1.0.2 - Do not create a new object if the object type does not match what the key thinks it should be (causes invalid results for array-like objects) ## 1.0.1 - Remove duplicate call to `isCloneable` (performance improvement when cloning) ## 1.0.0 - Initial release
